Requirements For Installing/Servicing R410A Equipment Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle the POE or PVE type oils. Manifold sets should be 800 PSIG high side and 250 PSIG low side with 550 PSIG Iow side restart. All hoses must have a 700 PSIG service pressure rating. Leak detectors should be designed to detect refrigerant. Recovery equipment (including refrigerant recovery containers) must be specifi- cally designed to handle R410A. Do not use an R-22 TXV. It will be more convenient to open the Service valve after removing the Underside Clpboard. see the Fig.1 Underside Clapboard LARGE SERVICE VALVE SMALL SERVICE VALVE 1.2 LIMITATIONS The unit should be installed in accordance with all National, State and Local Safety Codes and the limitations listed below: 1.Limitations for the indoor unit, coil and appropriate accessories must also be observed. 2.The outdoor unit must not be installed with any duct work in the air stream.
